Searching for an encrypted SD card means checking more than capacity: the card alone does not encrypt your files. Both picks here are iStorage microSD cards that rely on a separate datAshur SD drive to apply AES-XTS 256-bit hardware encryption when locked. I rank the single 128GB card first for buyers who need one compatible replacement or storage option, while the three-pack suits people who want multiple cards for a datAshur SD setup. The key tradeoff is straightforward: neither card is a standalone encrypted product, and using one in another device may affect its later operation with datAshur SD.

iStorage 128GB microSD Card for datAshur SD
I put this single-card option first because it is the clearest fit for someone who already owns, or plans to buy, an iStorage datAshur SD and needs one 128GB card. The security story is tied to that drive: with a compatible datAshur SD, card data receives AES-XTS 256-bit hardware encryption when locked. The microSD card itself is not a self-encrypting substitute for the drive, so buyers should not treat it as protected storage when removed and used elsewhere.
Compared with the three-pack, this listing keeps the decision simple: one card, one stated capacity, and no extra cards to manage. That makes it a more sensible starting point for a single storage set or a replacement card. The three-pack is more useful when a buyer wants separate cards for different files or workflows, but this single option avoids paying for unused capacity in the form of additional cards. I would choose based on how many distinct card-based storage sets the datAshur SD workflow actually needs.
The main limitation is strict compatibility. The description warns that the card may not work correctly with datAshur SD if it has been used in another device, so I would keep it dedicated to the intended system. The drive is sold separately, which adds a required component for anyone starting from scratch. I also would not infer speed or ruggedness from the supplied information; those details are not specified. Its role is narrow but useful: a dedicated 128GB card for buyers whose priority is a compatible encrypted-drive setup, not a general-purpose microSD card.
Pros:- Supports AES-XTS 256-bit hardware encryption when used with datAshur SD
- One 128GB card suits a single storage set
- Removable media lets the compatible setup use different supported card capacities
- The product line is available in capacities up to 1TB
Cons:- Requires a separately sold datAshur SD drive for encryption
- May not work correctly with datAshur SD after use in another device
- Intended compatibility is limited to datAshur SD
Best for: Someone who owns or intends to buy a datAshur SD drive and needs one dedicated 128GB microSD card.
Not ideal for: Buyers who need a standalone encrypted card, broad compatibility with cameras or phones, or several cards in one purchase.
- Card type:microSD
- Capacity:128GB
- Compatible device:iStorage datAshur SD encrypted USB flash drive
- Encryption:AES-XTS 256-bit hardware encryption with datAshur SD
- Encryption condition:Data is protected when the compatible drive is locked
- Drive included:No; sold separately
- Other available capacities:Up to 1TB
Our verdict“I recommend this single 128GB card for datAshur SD owners who want one dedicated encrypted-storage card without buying a multi-card pack.”
iStorage 128GB microSD Cards, 3-Pack, for datAshur SD Drives
This three-pack earns its place for buyers who want multiple compatible cards rather than a single storage set. Each card has 128GB capacity, and each relies on a compatible datAshur SD drive for AES-XTS 256-bit hardware encryption when locked. The bundle does not change the security method compared with the single card; its distinction is three separate cards for organizing files, keeping projects apart, or maintaining more than one card-based set.
Compared with the single-card pick, this option makes more sense when card quantity is part of the plan. It can reduce the need to source additional compatible cards later, but buyers should be clear that three cards do not mean three encryption systems or three included drives. The datAshur SD is still sold separately, and the security feature still depends on using the cards with that drive. If you only need one 128GB card, the first pick is the more focused choice; if you expect to rotate among several sets, this pack has the more useful configuration.
The same compatibility warning applies here: these cards are intended for datAshur SD drives only, and using them in another device may interfere with later use in the encrypted-drive setup. That makes the pack a poor choice for someone who wants removable cards to shuttle freely between a camera, computer, and secure drive. The available capacity range extends through 1TB options, but this particular bundle contains three 128GB cards. I would choose it for separation and spare-card convenience, not for a stronger encryption claim or broader device support.
Pros:- Three separate 128GB cards provide multiple storage sets
- Supports AES-XTS 256-bit hardware encryption with compatible datAshur SD drives
- Useful for separating projects or files across cards
- The product range includes capacities up to 1TB
Cons:- The datAshur SD drive is sold separately
- Cards are intended only for datAshur SD drives
- The three-card configuration may be unnecessary for buyers who need only one card
Best for: A datAshur SD owner who wants three dedicated 128GB cards for separate file groups, projects, or storage sets.
Not ideal for: Anyone who needs just one card, expects general-purpose device compatibility, or wants encryption without purchasing a datAshur SD drive.
- Card type:microSD
- Pack quantity:3 cards
- Capacity per card:128GB
- Compatible devices:iStorage datAshur SD drives
- Encryption:AES-XTS 256-bit hardware encryption with a compatible datAshur SD drive
- Encryption condition:Data is protected when the compatible drive is locked
- Drive included:No; sold separately
- Other available capacities:32GB, 64GB, 128GB, 256GB, 512GB, and 1TB
Our verdict“I would choose this pack over the single card only when having three dedicated 128GB cards matters more than keeping the purchase to one card.”
How We Picked
I ranked these two options by how clearly they fit the search for encrypted SD cards, while keeping the encryption dependency visible. The supplied details describe compatible microSD cards, not cards with independent encryption hardware: protection comes from a datAshur SD drive and applies when that drive is locked. I gave the single card the first spot because it is the more direct match for someone who needs one 128GB card. The three-pack follows for buyers who value having several compatible cards rather than a different encryption method.
I also weighed practical fit: capacity per card, pack quantity, compatibility limits, and the risk of using a card outside its intended system. The details provided do not specify read or write speeds, durability ratings, or separate card-level security controls, so I do not use those as ranking factors. Both options share the same central limitation: the drive is sold separately, and the cards are intended only for datAshur SD use. The ranking reflects purchase simplicity and intended use, not a claim that one card encrypts more strongly than the other.

Factors to Consider When Choosing Encrypted Sd Cards
Before choosing between these two listings, I would separate the question of encryption from the question of card quantity. Both depend on the same compatible drive, so the meaningful differences are how many cards you want, how you will keep them dedicated, and whether 128GB per card suits your files.Know where the encryption comes from
Neither listing describes a microSD card that encrypts files on its own. The supplied specifications tie AES-XTS 256-bit hardware encryption to use with an iStorage datAshur SD drive, with protection active when that drive is locked. If you are shopping for a card that can be moved between devices and keep data encrypted independently, neither product matches that requirement. Treat the compatible drive as a required part of the system, not an optional extra.
This distinction also shapes how I compare the two: they share the stated encryption arrangement, so the three-pack is not a more secure version of the single card. Its advantage is the number of cards. The single card has the same stated encryption relationship in a one-card configuration.
Choose one card or three
The single 128GB card is the straightforward pick for one storage set, a replacement, or someone who wants to begin with one dedicated card. The three-pack suits a buyer who wants separate cards for different projects or categories of files. Dividing data across cards can make a personal filing routine easier, but it does not replace backups and does not create additional protection by itself.
I would avoid buying three cards just because the bundle sounds more flexible. If you have no plan for the additional cards, the single-card option is a closer fit. Conversely, if you already use datAshur SD and know you want multiple card-based sets, the three-pack avoids treating each set as an unrelated compatibility purchase.
Keep compatibility narrow
Both listings are specifically intended for datAshur SD use. The single-card description warns that use in another device may affect whether it works correctly with the encrypted drive later; the three-pack likewise says the cards should only be used with datAshur SD drives. I would not plan to use these as everyday cards for cameras, phones, or readers unless the manufacturer confirms that workflow is supported.
That restriction is a practical tradeoff, not a minor footnote. Buyers who regularly move a card among devices should look for storage designed for that broader workflow. These picks are better understood as components in a dedicated secure-storage arrangement.
Match capacity to the job
Each card in these two listings is 128GB. The supplied product details mention other capacities in the iStorage range, up to 1TB, but that does not change the capacity of the single card or the cards in this three-pack. Think about how much data belongs on each individual card, especially if you intend to keep different projects separate.
The three-pack gives you three 128GB cards rather than one card with a combined capacity. That can be helpful when separation matters, but it is not equivalent to a single larger card for every workflow. If your main need is more room in one storage set, compare the relevant capacity option and confirm compatibility with datAshur SD before choosing.
Account for the separate drive
Both products require a separately sold datAshur SD drive for the described encryption. If you already own the compatible drive, choosing between these cards is mainly a question of quantity. If you do not own it, include the drive in your plan and verify that the complete setup fits your needs before buying a card on its own.
I would also keep the card dedicated to the encrypted-drive workflow. The supplied details do not list speed ratings, durability certifications, or independent card encryption, so I would not select either listing based on assumptions about those qualities. Their clearest documented purpose is compatible storage for the datAshur SD system.
Frequently Asked Questions
Do these microSD cards encrypt data by themselves?
No. The stated AES-XTS 256-bit hardware encryption is provided when a card is used with a compatible iStorage datAshur SD drive, and data is protected when that drive is locked. The cards alone should not be treated as self-encrypting storage.
Is the datAshur SD drive included with either product?
No. Both listings describe microSD cards for use with a datAshur SD drive, which is sold separately. A buyer who does not already own a compatible drive needs to account for that additional component to use the described encryption setup.
Which should I choose: the single card or the three-pack?
I would choose the single 128GB card for one storage set, a replacement, or a simpler purchase. The three-pack is better suited to datAshur SD owners who want three separate 128GB cards for different file groups or projects. The encryption arrangement is the same in both listings; the main difference is card quantity.
Can I use these cards in a camera, phone, or standard card reader?
The descriptions limit intended use to datAshur SD drives and warn against using the cards in other devices. In particular, the single-card description says another device may affect whether the card works correctly with datAshur SD afterward. I would keep either option dedicated to the compatible drive unless iStorage confirms another use is supported.
Are these available in capacities other than 128GB?
The listed single card and each card in the three-pack are 128GB. The product details mention other available capacities across the range, including options up to 1TB, but those are separate capacity choices rather than the configuration of these exact listings. Check that the chosen capacity works with your datAshur SD setup before buying.
Conclusion
For a buyer who needs one dedicated 128GB card for a datAshur SD drive, I recommend the single-card option: it keeps the choice focused and avoids extra cards. If you already have the drive and want three separate storage sets, the three-pack is the more practical fit. I would skip both if you need standalone encryption or broad use across cameras, phones, and other devices. In either case, the card is only one part of the encrypted-storage setup; the compatible datAshur SD drive is required for the stated protection.
